FHIR
Modern HTTP/JSON API for clinical data — the direction most vendors are heading.
FHIR (Fast Healthcare Interoperability Resources) is HL7's modern standard: a REST API with JSON resources for Patient, Encounter, Observation, Condition, etc. The 21st Century Cures Act effectively requires US EHRs to expose a FHIR API for patient access. "USCDI on FHIR" is the federal baseline of fields a vendor must support.
